Answer to Question 1
After young marsupials are born, they will travel up their mother's belly and into the pouch. Once inside
the pouch, the young will attach themselves to a nipple, where they are nourished. The young remain in the
pouch until they are strong enough to venture outside the pouch. They will return to the pouch for warmth
and nourishment.
Placental mammals do not have a pouch in which the young are raised.
Answer to Question 2
Marsupials have a pouch called a marsupium in which the young are raised during early infancy.
